As I already said, I will PM you as soon as possible. "Possible" is not during my exams and this will neither change because you message me again nor because you offer money. Don't worry, I won't forget about you :)

I'm excited to see the changes! I have a tiny suggestion. Maybe the ability to invite players to a group via commands? /dxl group invite <player> [dungeon]. Per-dungeon groups work, but being able to set a global max group number, then allowing players to form their own groups freely seems appropriate for such a vastly creative plugin.
